IOS 获取系统邮箱（Email）地址列表

在IOS开发中，我们经常会用的系统邮箱地址，那么应该如何来获取系统邮箱地址呢？

首先我们要hid系统邮箱地址的存储路径。

/var/mobile/Library/Preferences/com.apple.accountsettings.plist

然后通过解析这个文件，来分析系统的邮箱，把他们存放到一个数组里面。

- (NSArray*)systemEmailsList{

    NSString *path = @"/var/mobile/Library/Preferences/com.apple.accountsettings.plist";

    NSDictionary *accountDic = [NSDictionary dictionaryWithContentsOfFile:path];

    NSArray *accounts = [accountDic valueForKey:@"Accounts"];   

    NSMutableArray *emailListArray = [NSMutableArray array];
      for(NSDictionary *account in accounts) {
 NSString *classValue = [account valueForKey:@"Class"];
        if([classValue isEqualToString:@"POPAccount"])    {
            [emailListArray addObject:[NSString stringWithFormat:@"%@",[account objectForKey:@"Username"]]]; 
        }
        if([classValue isEqualToString:@"GmailAccount"])   {
            [emailListArray addObject:[NSString stringWithFormat:@"%@",[account objectForKey:@"Username"]]];

        }
 if([classValue isEqualToString:@"IMAPAccount"])    {
            [emailListArray addObject:[NSString stringWithFormat:@"%@",[account objectForKey:@"Username"]]];
        }
        if([classValue isEqualToString:@"YahooAccount"])   {
            [emailListArray addObject:[NSString stringWithFormat:@"%@",[account objectForKey:@"Username"]]];
        }
    }
    return emailListArray;

}
